Gram and Immortal

On a rainy night, at the end of the rusty rails, a steam train that shouldn't exist tore through the thick fog - its carriages were full of inhuman traces, its boilers were fueled by flesh and blood, and its passengers were ghosts wandering in the rifts of time and space. This train named "Night Owl" has no end, only eternal contract and betrayal. Erin Hawke is forced to embark on the same escape journey that her mother took thirty years ago. With a brass key and blood-stained last words, she breaks into the strange world deep in the train: the bewitching mirror phantom in the compartment, the monster steward cooking memories in the dining car, the giant beating heart in the boiler room... Every carriage is a trap that devours humanity. And she gradually discovered that the "gatekeeper" mission carried by the Hawke family for generations had already integrated her blood with the train.
